hope u like it

Cool stuff....I got mine 3.6 OCCT/prime stable with 1.39v with 4 cores but I cant seem to get anything else with either 3 or 4 cores...its like I hit a wall.
Mine taking a screenie of your bios showing the voltage and what stock voltage you 720 shows at bios?
Thanks

chew* · 03-16-2009, 11:39 AM

1.325 is the correct stock volts for the 720 BE regardless of what bios sets it at. Most likely a bug if set to auto, it's quite possible your software monitor is reporting incorectly or the bios incorrectly sets voltage......

It appears to be a problem with a few boards atm.

**shaolin95** · 03-16-2009, 11:44 AM

Got it. Yeah when I run stock cpu-z, bios and occt all show 1.25 and I can go to 3.2 or so at that.
My main issue right now is that 3.6 wall I am hitting.

I have just RMA my board because of the random freeze ups that I was having. Hopefully the new one wouldnt have the same problem.

Yaxo11, your chip is the only one I have seen that doesnt have 0904 batch but overclocks well. I also noticed something, your bankcyle timing is 33, shouldnt it be 8+21=29 ?

**yaxo11** · 03-16-2009, 01:53 PM

it is set to auto, i should change it, tnx

I returned my mobo because of the cold start issue when you overclock NB.

Did you get another one or just returned?

what bios were you using? I had that issue till I started running F3b. I had to do a complete reset of bios after the update.

**shaolin95** · 03-16-2009, 05:14 PM

Sweet I finally got it 3.7GHZ prime stable with 4 cores at CPU NV .200 and CPU Voltage .150.

**msimax** · 03-16-2009, 05:28 PM

excellent

I did try F3b to unlock a core of 720, but I didn't try NB overclocking. It was the 2nd core that was locked up, and there was a reason why it was locked up.
So, F3b took care of the cold boot issue?

I am able to get 2800NB 3.9ghz 4 cores 720BE to boot into windows, even froma cold boot. So far so good.

**yaxo11** · 03-16-2009, 09:51 PM

I am using F3B bioss,F3 is totaly unusable for me, is F4D any better

**bro20000** · 03-16-2009, 11:41 PM

Have found F4G to be the best bios for my system if that helps!

Where to get F4G?!... Cant understand why bios F3B hangs Vista64, turns the SO soo slow. I think it's something to do with SB regarding my hard-drives.

I'm with F4D, works fine but can't unlock the 4th core..

**bro20000** · 03-17-2009, 02:34 AM

With F4G u cant unlock four core but my system seems better memory wise! Bios Here! http://www.mediafire.com/file/2ozvyz...M79XTUD5AT.rar

chew* · 03-17-2009, 02:51 AM

F4g is "the best" bios for this board to date......newer bios's are being patched so that you can not unlock the 4th core......basically if you want support lose the extra core......if you want the extra core than you will have to deal with a premature bios......

**JohnMike** · 03-17-2009, 03:19 AM

Thank's Bro20000/chew*

Regarding OC the NB... You guys only need to raise the NB VID or another BIOS setting else?!

The key to NB clocking is a happy balance between ram speed and timings and nb speed and ddr volts/nb vid volts.......If you push you ram hard your likely to lose a little NB speed......If you push your NB hard your likely to lose a little ram speed/timing latency.......find the happy balance and your cpu will likely clock higher as well.

**shaolin95** · 03-17-2009, 04:09 AM

I wonder how hard would it be for someone to "fix" the beta bios to enable the fourth core. Right now at 3.7 stable with 4 cores I just dont feel like letting go but I wouldnt mind the extra performance of a newer bios. :-)

**bro20000** · 03-17-2009, 04:24 AM

I was thinking to same thing how hard would it be to fix the bios to enable 4th core! It would be a killer bios if so cos F4g is really good with x3 chips!

chew* · 03-17-2009, 04:24 AM

I dabble with bios's but its a hack job at best, I'm better at hex editing vga bioses.....motherboard bioses....there's alot more that can go wrong. I leave that to the pros.

**shaolin95** · 03-17-2009, 04:59 AM

I am sure there is some bios expert around like there used to be for my older DFI boards and the likes...finger's crossed. :-)
